FIELD

The present application generally relates to navigation methods and devices.

BACKGROUND

Navigation devices are traditionally utilized mainly in the areas of vehicle use, such as on cars, motorcycles, trucks, boats, etc. Alternatively, if such navigation devices are portable, they are further transferable between vehicles and/or useable outside the vehicle, for foot travel for example.

These devices are typically tailored to produce a route of travel based upon an initial position of the navigation device and a selected/input travel destination (end position), noting that the initial position could be entered into the device, but is traditionally calculated via GPS Positioning from a GPS receiver within the navigation device. Although routes can be calculated across different state and country boarders, no distinction is typically visible to a user, except for maybe the existence of a boundary line. Further, even if a country is entered in which the driving rules change, this is transparent to the user of the navigation device.

SUMMARY

The inventors have discovered that it may be desirable for a user of the navigation device to be warned when a route is planned in a country with driving rules different from a home country of the user. These driving rules include, for example, countries in which drivers drive on a different side than that of the user's home country (for example, in France drivers drive on the right side of the road, but in Great Britain drivers drive on the left side of the road). Thus, the inventors have discovered that a user may want to be alerted or warned when entering a country with driving rules different from a home country of the user, such as when entering a country where drivers drive on an opposite side of the road, for example.

In at least one embodiment of the present application, a method includes determining a route of travel, in a navigation device, based upon at least a received destination location; determining whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device; and prompting a user of the navigation device to enable a warning upon determining that the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of the user.

In at least one embodiment of the present application, a method includes determining a route of travel, in a navigation device, based upon at least a received destination location; determining whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device; and warning a user of the navigation device prior to entry into the country with at least one designated driving rule different from a home country of a user of the navigation device.

In at least one embodiment of the present application, a method includes determining a change of a home location of a user of a navigation device to a country with at least one designated driving rule different from a country of a current home location of the user; and prompting a user of the navigation device to enable a warning upon determining the change of the home location.

In at least one embodiment of the present application, a method includes determining a route of travel, in a navigation device, based upon at least a received destination location; determining whether or not the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of a user of the navigation device; and prompting a user of the navigation device to view the at least one designated driving rule of the another country upon determining that the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of the user.

In at least one embodiment of the present application, a navigation device includes a processor to determine a route of travel based upon at least a received destination location and to determine whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device; and an output device to prompt a user of the navigation device to enable a warning upon the processor determining that the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of the user.

In at least one embodiment of the present application, a navigation device includes a processor to determine a route of travel based upon at least a received destination location and to determine whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device; and an output device a warning a user of the navigation device prior to entry into the country with at least one designated driving rule different from a home country of a user of the navigation device.

In at least one embodiment of the present application, a navigation device includes a processor to determine a change of a home location of a user of a navigation device to a country with at least one designated driving rule different from a country of a current home location of the user; and an output device to prompt a user of the navigation device to enable a warning upon determining the change of the home location.

In at least one embodiment of the present application, a navigation device includes a processor to determine a route of travel based upon at least a received destination location and to determine whether or not the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of a user of the navigation device; and an output device to prompt a user of the navigation device to view the at least one designated driving rule of the another country upon the processor determining that the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of the user.

DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms “a”, “an”, and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes” and/or “including”, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

In describing example embodiments illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the disclosure of this patent specification is not intended to be limited to the specific terminology so selected and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner.

Referencing the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, example embodiments of the present patent application are hereafter described. Like numbers refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

FIG. 1 illustrates an example view of Global Positioning System (GPS), usable by navigation devices, including the navigation device of embodiments of the present application. Such systems are known and are used for a variety of purposes. In general, GPS is a satellite-radio based navigation system capable of determining continuous position, velocity, time, and in some instances direction information for an unlimited number of users.

Formerly known as NAVSTAR, the GPS incorporates a plurality of satellites which work with the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can relay their location to any number of receiving units.

The GPS system is implemented when a device, specially equipped to receive GPS data, begins scanning radio frequencies for GPS satellite signals. Upon receiving a radio signal from a GPS satellite, the device determines the precise location of that satellite via one of a plurality of different conventional methods. The device will continue scanning, in most instances, for signals until it has acquired at least three different satellite signals (noting that position is not normally, but can be determined, with only two signals using other triangulation techniques). Implementing geometric triangulation, the receiver utilizes the three known positions to determine its own two-dimensional position relative to the satellites. This can be done in a known manner. Additionally, acquiring a fourth satellite signal will allow the receiving device to calculate its three dimensional position by the same geometrical calculation in a known manner. The position and velocity data can be updated in real time on a continuous basis by an unlimited number of users.

As shown in FIG. 1, the GPS system is denoted generally by reference numeral 100. A plurality of satellites 120 are in orbit about the earth 124. The orbit of each satellite 120 is not necessarily synchronous with the orbits of other satellites 120 and, in fact, is likely asynchronous. A GPS receiver 140, usable in embodiments of navigation devices of the present application, is shown receiving spread spectrum GPS satellite signals 160 from the various satellites 120.

The spread spectrum signals 160, continuously transmitted from each satellite 120, utilize a highly accurate frequency standard accomplished with an extremely accurate atomic clock. Each satellite 120, as part of its data signal transmission 160, transmits a data stream indicative of that particular satellite 120. It is appreciated by those skilled in the relevant art that the GPS receiver device 140 generally acquires spread spectrum GPS satellite signals 160 from at least three satellites 120 for the GPS receiver device 140 to calculate its two-dimensional position by triangulation. Acquisition of an additional signal, resulting in signals 160 from a total of four satellites 120, permits the GPS receiver device 140 to calculate its three-dimensional position in a known manner.

FIG. 2 illustrates an example block diagram of electronic components of a navigation device 200 of an embodiment of the present application, in block component format. It should be noted that the block diagram of the navigation device 200 is not inclusive of all components of the navigation device, but is only representative of many example components.

The navigation device 200 is located within a housing (not shown). The housing includes a processor 210 connected to an input device 220 and a display screen 240. The input device 220 can include a keyboard device, voice input device, touch panel and/or any other known input device utilized to input information; and the display screen 240 can include any type of display screen such as an LCD display, for example. In at least one embodiment of the present application, the input device 220 and display screen 240 are integrated into an integrated input and display device, including a touchpad or touchscreen input wherein a user need only touch a portion of the display screen 240 to select one of a plurality of display choices or to activate one of a plurality of virtual buttons.

In addition, other types of output devices 241 can also include, including but not limited to, an audible output device. As output device 241 can produce audible information to a user of the navigation device 200, it is equally understood that input device 240 can also include a microphone and software for receiving input voice commands as well.

In the navigation device 200, processor 210 is operatively connected to and set to receive input information from input device 240 via a connection 225, and operatively connected to at least one of display screen 240 and output device 241, via output connections 245, to output information thereto. Further, the processor 210 is operatively connected to memory 230 via connection 235 and is further adapted to receive/send information from/to input/output (I/O) ports 270 via connection 275, wherein the I/O port 270 is connectible to an I/O device 280 external to the navigation device 200. The external I/O device 270 may include, but is not limited to an external listening device such as an earpiece for example. The connection to I/O device 280 can further be a wired or wireless connection to any other external device such as a car stereo unit for hands-free operation and/or for voice activated operation for example, for connection to an ear piece or head phones, and/or for connection to a mobile phone for example, wherein the mobile phone connection may be used to establish a data connection between the navigation device 200 and the internet or any other network for example, and/or to establish a connection to a server via the internet or some other network for example.

The navigation device 200, in at least one embodiment, may establish a “mobile” network connection with the server 302 via a mobile device 400 (such as a mobile phone, PDA, and/or any device with mobile phone technology) establishing a digital connection (such as a digital connection via known Bluetooth technology for example). Thereafter, through its network service provider, the mobile device 400 can establish a network connection (through the internet for example) with a server 302. As such, a “mobile” network connection is established between the navigation device 200 (which can be, and often times is mobile as it travels alone and/or in a vehicle) and the server 302 to provide a “real-time” or at least very “up to date” gateway for information.

The establishing of the network connection between the mobile device 400 (via a service provider) and another device such as the server 302, using the internet 410 for example, can be done in a known manner. This can include use of TCP/IP layered protocol for example. The mobile device 400 can utilize any number of communication standards such as CDMA, GSM, WAN, etc.

As such, an internet connection may be utilized which is achieved via data connection, via a mobile phone or mobile phone technology within the navigation device 200 for example. For this connection, an internet connection between the server 302 and the navigation device 200 is established. This can be done, for example, through a mobile phone or other mobile device and a GPRS (General Packet Radio Service)-connection (GPRS connection is a high-speed data connection for mobile devices provided by telecom operators; GPRS is a method to connect to the internet.

The navigation device 200 can further complete a data connection with the mobile device 400, and eventually with the internet 410 and server 302, via existing Bluetooth technology for example, in a known manner, wherein the data protocol can utilize any number of standards, such as the GSRM, the Data Protocol Standard for the GSM standard, for example.

The navigation device 200 may include its own mobile phone technology within the navigation device 200 itself (including an antenna for example, wherein the internal antenna of the navigation device 200 can further alternatively be used). The mobile phone technology within the navigation device 200 can include internal components as specified above, and/or can include an insertable card, complete with necessary mobile phone technology and/or an antenna for example. As such, mobile phone technology within the navigation device 200 can similarly establish a network connection between the navigation device 200 and the server 302, via the internet 410 for example, in a manner similar to that of any mobile device 400.

For GRPS phone settings, the Bluetooth enabled device may be used to correctly work with the ever changing spectrum of mobile phone models, manufacturers, etc., model/manufacturer specific settings may be stored on the navigation device 200 for example. The data stored for this information can be updated in a manner discussed in any of the embodiments, previous and subsequent.

FIG. 2 further illustrates an operative connection between the processor 210 and an antenna/receiver 250 via connection 255, wherein the antenna/receiver 250 can be a GPS antenna/receiver for example. It will be understood that the antenna and receiver designated by reference numeral 250 are combined schematically for illustration, but that the antenna and receiver may be separately located components, and that the antenna may be a GPS patch antenna or helical antenna for example.

Further, it will be understood by one of ordinary skill in the art that the electronic components shown in FIG. 2 are powered by power sources (not shown) in a conventional manner. As will be understood by one of ordinary skill in the art, different configurations of the components shown in FIG. 2 are considered within the scope of the present application. For example, in one embodiment, the components shown in FIG. 2 may be in communication with one another via wired and/or wireless connections and the like. Thus, the scope of the navigation device 200 of the present application includes a portable or handheld navigation device 200.

In addition, the portable or handheld navigation device 200 of FIG. 2 can be connected or “docked” in a known manner to a motorized vehicle such as a car or boat for example. Such a navigation device 200 is then removable from the docked location for portable or handheld navigation use.

FIG. 3 illustrates an example block diagram of a server 302 and a navigation device 200 of the present application, via a generic communications channel 318, of an embodiment of the present application. The server 302 and a navigation device 200 of the present application can communicate when a connection via communications channel 318 is established between the server 302 and the navigation device 200 (noting that such a connection can be a data connection via mobile device, a direct connection via personal computer via the internet, etc.).

The server 302 includes, in addition to other components which may not be illustrated, a processor 304 operatively connected to a memory 306 and further operatively connected, via a wired or wireless connection 314, to a mass data storage device 312. The processor 304 is further operatively connected to transmitter 308 and receiver 310, to transmit and send information to and from navigation device 200 via communications channel 318. The signals sent and received may include data, communication, and/or other propagated signals. The transmitter 308 and receiver 310 may be selected or designed according to the communications requirement and communication technology used in the communication design for the navigation system 200. Further, it should be noted that the functions of transmitter 308 and receiver 310 may be combined into a signal transceiver.

Server 302 is further connected to (or includes) a mass storage device 312, noting that the mass storage device 312 may be coupled to the server 302 via communication link 314. The mass storage device 312 contains a store of navigation data and map information, and can again be a separate device from the server 302 or can be incorporated into the server 302.

The navigation device 200 is adapted to communicate with the server 302 through communications channel 318, and includes processor, memory, etc. as previously described with regard to FIG. 2, as well as transmitter 320 and receiver 322 to send and receive signals and/or data through the communications channel 318, noting that these devices can further be used to communicate with devices other than server 302. Further, the transmitter 320 and receiver 322 are selected or designed according to communication requirements and communication technology used in the communication design for the navigation device 200 and the functions of the transmitter 320 and receiver 322 may be combined into a single transceiver.

Software stored in server memory 306 provides instructions for the processor 304 and allows the server 302 to provide services to the navigation device 200. One service provided by the server 302 involves processing requests from the navigation device 200 and transmitting navigation data from the mass data storage 312 to the navigation device 200. According to at least one embodiment of the present application, another service provided by the server 302 includes processing the navigation data using various algorithms for a desired application and sending the results of these calculations to the navigation device 200.

The communication channel 318 generically represents the propagating medium or path that connects the navigation device 200 and the server 302. According to at least one embodiment of the present application, both the server 302 and navigation device 200 include a transmitter for transmitting data through the communication channel and a receiver for receiving data that has been transmitted through the communication channel.

The communication channel 318 is not limited to a particular communication technology. Additionally, the communication channel 318 is not limited to a single communication technology; that is, the channel 318 may include several communication links that use a variety of technology. For example, according to at least one embodiment, the communication channel 318 can be adapted to provide a path for electrical, optical, and/or electromagnetic communications, etc. As such, the communication channel 318 includes, but is not limited to, one or a combination of the following: electric circuits, electrical conductors such as wires and coaxial cables, fiber optic cables, converters, radio-frequency (rf) waves, the atmosphere, empty space, etc. Furthermore, according to at least one various embodiment, the communication channel 318 can include intermediate devices such as routers, repeaters, buffers, transmitters, and receivers, for example.

In at least one embodiment of the present application, for example, the communication channel 318 includes telephone and computer networks. Furthermore, in at least one embodiment, the communication channel 318 may be capable of accommodating wireless communication such as radio frequency, microwave frequency, infrared communication, etc. Additionally, according to at least one embodiment, the communication channel 318 can accommodate satellite communication.

The communication signals transmitted through the communication channel 318 include, but are not limited to, signals as may be required or desired for given communication technology. For example, the signals may be adapted to be used in cellular communication technology such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), etc. Both digital and analogue signals can be transmitted through the communication channel 318. According to at least one embodiment, these signals may be modulated, encrypted and/or compressed signals as may be desirable for the communication technology.

The mass data storage 312 includes sufficient memory for the desired navigation applications. Examples of the mass data storage 312 may include magnetic data storage media such as hard drives for example, optical storage media such as CD-Roms for example, charged data storage media such as flash memory for example, molecular memory, etc.

According to at least one embodiment of the present application, the server 302 includes a remote server accessible by the navigation device 200 via a wireless channel. According to at least one other embodiment of the application, the server 302 may include a network server located on a local area network (LAN), wide area network (WAN), virtual private network (VPN), etc.

According to at least one embodiment of the present application, the server 302 may include a personal computer such as a desktop or laptop computer, and the communication channel 318 may be a cable connected between the personal computer and the navigation device 200. Alternatively, a personal computer may be connected between the navigation device 200 and the server 302 to establish an internet connection between the server 302 and the navigation device 200. Alternatively, a mobile telephone or other handheld device may establish a wireless connection to the internet, for connecting the navigation device 200 to the server 302 via the internet.

The navigation device 200 may be provided with information from the server 302 via information downloads which may be periodically updated upon a user connecting navigation device 200 to the server 302 and/or may be more dynamic upon a more constant or frequent connection being made between the server 302 and navigation device 200 via a wireless mobile connection device and TCP/IP connection for example. For many dynamic calculations, the processor 304 in the server 302 may be used to handle the bulk of the processing needs; however, processor 210 of navigation device 200 can also handle much processing and calculation, oftentimes independent of a connection to a server 302.

The mass storage device 312 connected to the server 302 can include volumes more cartographic and route data than that which is able to be maintained on the navigation device 200 itself, including maps, etc. The server 302 may process, for example, the majority of the devices of a navigation device 200 which travel along the route using a set of processing algorithms. Further, the cartographic and route data stored in memory 312 can operate on signals (e.g. GPS signals), originally received by the navigation device 200.

A navigation device 200 of an embodiment of the present application includes a processor 210 and an integrated input and display device, integrating the input device 220 and display screen 240 of the navigation device 200, and including a touchscreen input wherein a user need only touch a portion of the display screen 240 to select one of a plurality of display choices or to activate one of a plurality of displayed virtual buttons. In the navigation device 200 of an embodiment of the present application, the processor 210 is used to determine a route of travel based upon at least a received destination location (input by a user for example, in planning a route) and to determine whether or not the determined route of travel includes travel on a limited access road (such as; and an integrated input and display device to prompt a user of the navigation device 200 to either accept the determined route of travel or request an alternate route of travel, upon the processor determining that the determined route of travel includes travel on a limited access road.

As indicated above in FIG. 2 of the application, a navigation device 200 of an embodiment of the present application includes a processor 210, an input device 220, and a display screen 240. In at least one embodiment, the input device 220 and display screen 240 are integrated into an integrated input and display device to enable both input of information (via direct input, menu selection, etc.) and display of information through a touch panel screen, for example. Such a screen may be a touch input LCD screen, for example, as is well known to those of ordinary skill in the art. Further, the navigation device 200 can also include any additional input device 220 and/or any additional output device 241, such as audio input/output devices for example.

FIGS. 4A and 4B are perspective views of an implementation of an embodiment of the navigation device 200. As shown in FIG. 4A, the navigation device 200 may be a unit that includes an integrated input and display device 290 (a touch panel screen for example) and the other components of FIG. 2 (including but not limited to internal GPS receiver 250, microprocessor 210, a power supply, memory systems 220, etc.).

The navigation device 200 may sit on an arm 292, which itself may be secured to a vehicle dashboard/window/etc. using a large suction cup 294. This arm 292 is one example of a docking station to which the navigation device 200 can be docked.

The navigation device 200 may then be rotatable on the arm 292, as shown by the arrow of FIG. 4B. To release the connection between the navigation device 200 and the docking station, a button on the navigation device 200 may be pressed, for example (this is only one example, as other known alternatives for disconnection to a docking station are within the scope of the present application).

In at least one embodiment of the present application, a method of the present application includes determining a route of travel, in a navigation device 200, based upon at least a received destination location; determining whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device 200; and prompting a user of the navigation device 200 to enable a warning upon determining that the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of the user.

Initially, a route of travel is first determined in step S2 by the processor 210 for example, based upon at least a received destination location. Typically, a current location of the navigation device 200 is received via a GPS receiver within the navigation device 200. From the destination location and the current location of the navigation device 200, a route of travel can be calculated in a known manner using stored map information.

Thereafter, in step S4, the processor 210 determines whether or not the route of travel includes travel in a country with at least one designated driving rule different from the home country of the user of the navigation device 200. For example, such designated driving rules can include, but are not limited to, which side of the road cars drive on in that country, upon what unit of measure is vehicle speed limit based, etc.

In determining the route, country borders can be flagged such that border crossing flags can be detected by the processor 210 upon determining the route of travel. Further, once flagged, a country in which the borders to be crossed, based upon the determined route of travel, has designated driving rules of its country compared with that of a home country of the user, registered upon the user buying the device for example. Based upon such a comparison, the processor 210 can determine whether or not the route of travel includes travel in a country with at least one different designated driving rule.

If the determination in step S4 is no, the method proceeds to step S6 wherein the determined route for travel is output in a normal fashion. However, if the result in step S4 is yes, the user is prompted to enable a warning. Such a prompt can include displaying a plurality of selections to a user, for example on an integrated input and display device 290, including at least one selection to enable output of the warning and at least one selection to disable output of the warning. One example of such a display is shown in FIG. 6 of the present application.

As shown in FIG. 6, the displaying can include displaying a plurality of selections to the user, for example on an integrated input and display device 290, including at least one selection to enable the warning when driving in a right-side driving country, and at least one selection to enable the warning when driving in a left-side driving country. Further, at least one selection may be included to disable output of the warning, such as the “don't warn me” selection shown in FIG. 6.

Returning to FIG. 5, shown in step S10, if the warning has been enabled, the warning may be output, via out device 241 for example, upon receiving an indication of the selection to enable the warning in Step S8 and upon determining there is at least one parameter governing output of the warning is met.

Such a parameter may include at least one of a time parameter and a distance parameter. For example, as shown in FIG. 7, upon determining a route of travel based upon received inputs in step S2, the processor 210 may determine that the route of travel includes a country with different designated driving rules, by determining the appearance of a border crossing flag along the calculated route of travel as shown in FIG. 7, and then upon determining that the border crossing flag designates a border with at least one different designated driving rule. As the border crossing flag location is known, the parameter governing output of the warning can be a designated time before the border crossing flag is due to be reached or a designated distance before the particular border is reached. Such time and distance parameters (such as after different time intervals and/or after certain distance intervals both before entering and after entering the country) can be designated upon creation of the navigation device 200 or upon programming the processor 210 for example.

As indicated previously in FIG. 5, a warning may be output in step S10, during travel along the route. Such an output may include a visual output such as that shown in FIG. 8, warning the user to drive on the right side of the road (assuming that the user had a location in Great Britain, for example, wherein the user would typically drive on the left side of the road). FIG. 8 merely provides one example of such a warning, noting that the warning cannot only be displayed on an integrated input and display device 290 similar to that shown in FIG. 8, but can also be an audible output. This further may include flashing at least part of the warning and/or icon, or otherwise distinguishing or differentiating at least one of the warning message and/or icon from that previously displayed.

The above described example of FIGS. 5-8 has been described with the example of the designated driving rule being that of a right-side driving country or a left-side driving country. However, the driving rule may be one of any other rules including, for example, whether or not a vehicle speed limit is based in a unit of measure different from a home country of the user of the navigation device 200. For example, certain countries display measured vehicle speed limit in terms of kilometers per hour, while other countries measure vehicle speed limit in miles per hour. Thus, the prompting in step S6 can include displaying a plurality of selections to the user, including a selection to warn the user of the navigation device 200 that the vehicle speed limit is based in a unit of measure different from a home country of the user of the navigation device 200.

It should be noted that each of the aforementioned aspects of an embodiment of the present application have been described with regard to the method of the present application. However, at least one embodiment of the present application is directed to a navigation device 200, including a processor 210 to determine a route of travel based upon at least a received destination location and to determine whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device 200; and an output device 241 to prompt a user of the navigation device 200 to enable a warning upon the processor determining that the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of the user. Thus, such a navigation device 200 may be used to perform the various aspects of the method described with regard to FIGS. 5-8, as would be understood by one of ordinary skill in the art. Thus, further explanation is omitted for the sake of brevity.

Another embodiment of the present application is directed to a method including determining a route of travel, in a navigation device 200, based upon at least a received destination location; determining whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from the home country of a user of the navigation device 200; and warning a user of the navigation device 200 prior to entry in the country with at least one designated driving rule different from a home country of the user of the navigation device 200.

An example of such an embodiment of the present application is shown in FIG. 9 for example. In step S20, the processor 210 determines the route of travel and determines whether or not the determined travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device 200, in a manner somewhat similar to that of FIG. 5 of the present application. Upon making such a determination, a route map summary review, indicating the location of a border along the route may be displayed in step S22. Instead of merely prompting a user to enable a warning as discussed previously with regard to FIG. 5, the user may instead be warned prior to entry into the country with at least one designated driving rule different from a home country of the user of the navigation device 200, by a warning such as shown in step S24 of FIG. 9 for example. Thus, one way of warning the user may be displaying a warning, on an integrated input and display device 290 for example, indicating the country to be entered as a country with a rule for driving on the side of the road opposite from that in the home country of a user of the navigation device 200; or in the case of the rule being that of different measures of speed limits for example, the warning can include displaying a warning indicating that the country to be entered is a country with a vehicle speed limit based in the unit of measure different from the home country of the user of the navigation device 200.

Similar to that previously stated with FIGS. 5-8 of the present application, the warning may be displayed upon determining that at least one of a time parameter and distance parameter as met, wherein the warning may be displayed a plurality of times, after each of a plurality of different parameters are met (such as after different time intervals and/or after certain distance intervals both before entering and after entering the country). Additionally, although the warning is shown in a display format in step S24 of FIG. 9, it should be understood that the warning may be output at least one of visually and audibly.

It should further be noted that if a user of the navigation device 200 is planning a route that starts in a country where at least one designated driving rule is different from a home country of the user of the navigation device 200, the user of the navigation device 200 may be warned subsequent to entry into the country where at least one designated driving rule different from the user of the navigation device 200, namely immediately after the processor 210 determining the route of travel and determining that the route includes travel in a country with at least one designated driving rule different from the user of the navigation device 200. Thus, the warning would be output shortly after the route is determined, before the user even begins to use the navigation device 200 for travel.

Further, it should be noted that depending on how the various rules are set, the user may be notified upon entry into the country with at least one designated driving rule different from a home country of the user of the navigation device 200.

It should be noted that each of the aforementioned aspects of an embodiment of the present application have been described with regard to the method of the present application. However, at least one embodiment of the present application is directed to a navigation device 200, including a processor 210 to determine a route of travel based upon at least a received destination location and to determine whether or not the determined route of travel includes travel in a country with at least one designated driving rule different from a home country of a user of the navigation device 200; and an output device 241 to warn a user of the navigation device 200 prior to entry into the country with at least one designated driving rule different from a home country of a user of the navigation device 200. Thus, such a navigation device 200 may be used to perform the various aspects of the method described with regard to FIG. 9, as would be understood by one of ordinary skill in the art. Thus, further explanation is omitted for the sake of brevity.

In another embodiment of the present application, a method includes determining a change of home location of the user of the navigation device 200 to a country with at least one designated driving rule different from a country of a current home location of the user and prompting the user of the navigation device 200 to enable a warning upon determining the change of the home location.

One example of the aforementioned method is shown in FIG. 10 of the present application. As shown in FIG. 10, it is initially determined in step S30, by processor 210 for example, if the user has changed his home location. For example, a user may register his home location typically subsequent to purchasing the navigation device 200, when the home location is stored in the memory 230 of the navigation device 200 itself. However, if a user moves to a new permanent residence for example, the user will typically enter a new home location. Upon entry of such a new home location, the method of an embodiment of the present application may determine the change of home location and then may be able to compare designated driving rules of a country of a current home location with the country of a previous home location. If there is no home location change, normal operation is continued in step S32. However, if there is a change in home location, the process moves to step S34 where the processor 210 determines whether or not the home location is changed to a country with at least one designated driving rule different from a country of a previous home location of the user. If not, the process continues normally in step S36.

If so, a user of the navigation device 200 is prompted to enable a warning upon the processor 210 determining the change of home location, wherein the prompting can include a display such as that as shown in step S38 of FIG. 10. The display can be one similar to that of FIG. 6, for example, including displaying a plurality of selections to the user, including at least one selection to enable output of the warning and at least one selection to disable an output of the warning (such as the “don't warn me” selection shown in step S38 for example), and/or the prompting may include the displaying of a plurality of selections including at least one selection to enable the warning when driving in a right side country (as shown the selected item in step S38 for example) and at least one selection to enable the warning when driving in a left side country (shown as an unselected displayed item in step S38 for example).

Thereafter, the warning may be output upon receiving an indication of a selection to enable the warning and upon determining that at least one parameter governing output of the warning is met. Such a parameter may include at least one of a time parameter and a distance parameter, wherein the warning is outputtable a plurality of times after each of a plurality of different parameters are met, for example, in a manner somewhat similar to that previously described with regard to another embodiment. Further, the outputting of a warning may be at least one of visual and audible, in a manner somewhat similar to that previously described.

Finally, the prompting may include not only displaying a plurality of selection relating to right-side and left-side driving countries, but may also include displaying a plurality of selections to the user including a selection to warn the user of the navigation device 200 that a vehicle speed limit is based in a unit of measure differ from a previous home country of the user of the navigation device 200.

FIG. 11 illustrates a slight alteration from that of FIG. 10. Namely, if it is determined by the processor 210 that a home location is changed to a country with different designated rules than that of a previous home location, the user may be prompted to enable a warning determining the change of a home location in a different manner as shown by step S37 of FIG. 11. Here, if a warning regarding left-side/right-side driving countries has been previously enabled, the prompt to enable the warning displayed to the user may request if the user would like to change the enabled warning prompt. If not, the system would continue normally in step S39, and if so, the selections of step S38 may be displayed.

It should be noted that each of the aforementioned aspects of an embodiment of the present application have been described with regard to the method of the present application. However, at least one embodiment of the present application is directed to a navigation device 200, including a processor 210 to determine a change of a home location of a user of a navigation device 200 to a country with at least one designated driving rule different from a country of a current home location of the user; and an output device 241 to prompt a user of the navigation device 200 to enable a warning upon determining the change of the home location. Thus, such a navigation device 200 may be used to perform the various aspects of the method described with regard to FIGS. 10 and 11, as would be understood by one of ordinary skill in the art. Thus, further explanation is omitted for the sake of brevity.

In yet another embodiment of the present application, a method includes determining a route of travel, in a navigation device 200, based upon at least a received destination location; determining whether or not the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of a user of the navigation device 200 and prompting a user of the navigation device 200 to view the at least one designated driving rule of the other country upon determining that the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of the user.

An example of such a method is shown in FIG. 12. In FIG. 12, a navigation route of travel is initially determined in step S40 in a manner similar to that previously described. Thereafter, in step S42, the processor 210 determines whether or not the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of the user of the navigation device 200 in step S42 in a manner somewhat similar to that previously described. Thereafter, however, the user is prompted in step S44 to view at least one designated driving rule of at least one other country along the current route. For example, the prompt may include, as shown in Step S46, displaying a plurality of selections to a user including at least one selection for viewing driving rules of at least one other country such as Spain for example, and at least one selection for viewing driving rules of the home country, such as The Netherlands, for example.

Thereafter, in step S48, driving rules for a selected country may be displayed, upon the processor 210 of the navigation device 200 receiving an indication of a selection of a displayed country, via an integrated input and display device 290 b displaying that shown in step S46 for example. The rules will typically include a summary of important rules for a particular country to be entered during the determined route of travel, wherein rules can be scrolled through if necessary, and wherein, if more than one country is to be traveled through, the various countries can be displayed and scrolled through if necessary (see step 46), wherein the prompting thus includes displaying a selection for viewing driving rules of each country included in the determined route of travel.

FIG. 13 lists one example of a display of road rules in a known country, wherein the display may include symbols and/or examples of the rules. The fourth panel of FIG. 13 further includes display of a “go to next country” button, wherein rules for next country may then be thereafter displayed. Thus, the displaying may include at least one of symbols and examples of the rules.

It should be noted that each of the aforementioned aspects of an embodiment of the present application have been described with regard to the method of the present application. However, at least one embodiment of the present application is directed to a navigation device 200, including a processor 210 to determine a route of travel based upon at least a received destination location and to determine whether or not the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of a user of the navigation device 200; and an output device 241 to prompt a user of the navigation device 200 to view the at least one designated driving rule of the another country upon the processor 210 determining that the determined route of travel includes travel in another country with at least one designated driving rule different from a home country of the user. Thus, such a navigation device 200 may be used to perform the various aspects of the method described with regard to FIG. 13, as would be understood by one of ordinary skill in the art. Thus, further explanation is omitted for the sake of brevity.
